You have no business on either of those frequencies.

Depends upon where you are.

433mhz is a SHARED ham band throughout the world.

In ITU zone 1 and possibly elsewhere, there is a small allocation
of 433mHz for unlicensed devices.

There also is one at 315mHz, but that may be a different part of the world.

It is used for wireless doorbells, security systems, etc. Basicly low power
unlicensed telemetry.

If you look on eBay, you will find hundreds of the devices. A quick web search
shows the 433 mHz units sold in the US.
